Replaced spark plugs with bosch platinum 2. Which I know is supposedly not supposed to hurt it. After the fact turned on the car and let it sit for 30 minutes. Took for a drive and has a hard idle with a shaky start but betters during drive. I took it at low speeds and at high and still there is a problem. I know to get my engine read which auto zone will do for free and I checked the plug wires themselves but they appeared normal. Im completely lost and need advice. Thanks

Is it hard starting and miss firing? Is your check engine light on?
